Gyaros Island Marine Protected Area (Nisos Gyaros kai Thalassia Zoni)

The uninhabited island of Gyaros in the northern Cyclades and its surrounding 3-nautical-mile marine zone are designated as a Natura 2000 site (GR4220033) and, since 2019, a formally managed Marine Protected Area. A Presidential Decree issued on 16 April 2026 permanently codified the protection zones and management rules. Following a brief and damaging opening in summer 2022, the MPA was upgraded to a full no-take zone (NTZ) with all fishing—including recreational spearfishing—banned throughout the protected marine area; the Hellenic Coast Guard enforces the ban with a remote surveillance system (radar, infrared cameras, drones).
